Guest danderson500 Posted September 9, 2015 Share Posted September 9, 2015 why are we still getting storms? why wont it quiet down? Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 9, 2015 Share Posted September 9, 2015 Because the direction of the IMF (Bz) continues to trend southwards occasionally likely due to lingering CME effects. Link to comment Share on other sites More sharing options...
Guest danderson500 Posted September 9, 2015 Share Posted September 9, 2015 are we sure it is because of a CME because i didn't see one Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 9, 2015 Share Posted September 9, 2015 It is likely a coronal mass ejection from a few days ago which was mostly heading south of the ecliptic. It was a slow CME, not much faster than the ambient solar wind. Explains the long lasting effects. Link to comment Share on other sites More sharing options...
Guest danderson500 Posted September 9, 2015 Share Posted September 9, 2015 i am kind of worried about the coronal hole later in the week was asking are expecting anything bad from from the CIR or the coronal hole so the CME's we are getting are slower than usal?

Maxime Fiset Posted September 9, 2015 Share Posted September 9, 2015 i am kind of worried about the coronal hole later in the weekwas asking are expecting anything bad from from the CIR or the coronal holeNo. The CIR/Coronal hole are nowhere strong enough to cause anything bad.so the CME's we are getting are slower than usal?It so happened that way. Could be different, could happen again. We can't predict the speed/density of the next CME. Don't worry, you will know as soon as we do if anything interesting was bound to happen =) Link to comment Share on other sites More sharing options...
Guest danderson500 Posted September 9, 2015 Share Posted September 9, 2015 NOAA says there was a flimanet erupton this morning.. do we know yet what it was? Link to comment Share on other sites More sharing options...
Maxime Fiset Posted September 9, 2015 Share Posted September 9, 2015 NOAA says there was a flimanet erupton this morning.. do we know yet what it was?A filament eruption is much less "interesting" than a full-halo CME for you, my friend. From what I've understood, a filament eruption is just that : an eruption that lacks sufficient power to erupt a large mass of plasma at a time. Think of it as a soda bottle. If you make it explode, you'll end up with 60 ounces of pop on the floor in a very short period of time. If you shake it and pierce a small hole, you'll end up with 20-30 ounces of pop spread in a "filament" over a much longer period of time. This filament (or the one before, there was one like 1-2 days ago) could be the CME causing the lingering geomagnetic storm. Link to comment Share on other sites More sharing options...

Guest danderson500 Posted September 10, 2015 Share Posted September 10, 2015 why is everyone thinking the coronal hole is causing a G2 when it is the CME that is causing it? Link to comment Share on other sites More sharing options...
Maxime Fiset Posted September 10, 2015 Share Posted September 10, 2015 why is everyone thinking the coronal hole is causing a G2 when it is the CME that is causing it?Because it is both. Link to comment Share on other sites More sharing options...
Guest danderson500 Posted September 11, 2015 Share Posted September 11, 2015 why was it g3? i tough it would be a lesser storm? question are going to get a carrigton event from the coronal hole? Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 11, 2015 Share Posted September 11, 2015 Really danderson we are not going to repeat ourselves a million times over. Consider this a friendly warning. It's borderline spamming what you are doing. A geomagnetic storm that has the strength of the Carrington event occurs very very very rarely. Once every few hundred years perhaps. It was caused by an extreme coronal mass ejection with a speed much higher than any coronal hole solar wind stream will ever reach. Like we said the previous 999.999 times: there is nothing for you to worry about. The world will still be here as you know it when you wake up tomorrow.

Guest danderson500 Posted September 11, 2015 Share Posted September 11, 2015 but i am asking why are we getting a G3 when it should be G2 Link to comment Share on other sites More sharing options...
Marcel de Bont Posted September 11, 2015 Share Posted September 11, 2015 but i am asking why are we getting a G3 when it should be G2Why should it be G2? Just because it's predicted? Predictions are just that, an educated guess. Sometimes a storm can turn out weaker or stronger then expected. We never exactly know what is coming towards us until it reached ACE.

Guest danderson500 Posted September 11, 2015 Share Posted September 11, 2015 NOAA just said that the wind stream is beginning to weaken so i guess just G1 rest of today Link to comment Share on other sites More sharing options...
Maxime Fiset Posted September 11, 2015 Share Posted September 11, 2015 Okay danderson, save this chart for future use : G1 : Pff, who cares?G2 : Possible auroras!G3 : Oooh, shiny, auroras!G4 : Well, that's gonna be a show!G5 : Interesting, I could use a free day to watch events unfold... and fill up my gas tank.G5+ : Well, perharps I could also fill my bathtub with water... G5+ is when a BIG CME is headed towards us. Every year, we have like 1/30 chance that this might happen, and this big CME won't even be Carrington-class. Considering the present geopolitical level of conflict, we also get like 1/20 chance that something ELSE might happen, like the hacking of the power grid, a nuclear EMP or just a good ol'war. Really, it is not the sun that should worry you. Link to comment Share on other sites More sharing options...

Marcel de Bont Posted October 7, 2015 Share Posted October 7, 2015 the predicted kp index The predicted Kp index is just that. A prediction made by a computer based on the ACE solar wind data. It could be wrong it could be right. Take it with a bit of salt, it's just that: a prediction. Link to comment Share on other sites More sharing options...
